Arabic Lots & Parts Calculator
Enter your birth details to calculate the 7 Hermetic Lots, also called Arabic Parts, plus Marriage and Exaltation.
What Are Arabic Lots and Parts?
Arabic parts (also called Arabic lots or Hermetic lots) are sensitive points in a birth chart calculated from three factors: usually the Ascendant plus two planetary positions. They originated in Hellenistic astrology and were transmitted through medieval Arabic-language texts, which is how they got their modern name.
The 7 Hermetic Lots form a planet-keyed set. Each lot is tied to one of the seven visible planets and addresses a specific topic drawn from that planet's symbolism. This calculator also includes the Lot of Marriage and Lot of Exaltation as additional traditional lots. The Part of Fortune and Lot of Spirit are the most widely known, while the remaining lots add detail about desire, obligation, boldness, success, trials, partnership, and eminence.
The 7 Hermetic Lots at a Glance
Each Hermetic Lot is associated with a classical planet and reveals a distinct life theme. The Part of Fortune (Moon) shows material luck and bodily circumstances. The Lot of Spirit (Sun) shows willpower and conscious purpose. The Lot of Eros (Venus) shows desire, love, and creative passion. The Lot of Necessity(Mercury) shows duty, obligation, and fate's constraints. The Lot of Courage (Mars) shows boldness and initiative. The Lot of Victory (Jupiter) shows success and achievement. The Lot of Nemesis (Saturn) shows tests, hardship, and growth through difficulty.
The formulas for all seven lots depend on whether you have a day chart (Sun above the horizon) or a night chart (Sun below). This calculator detects your sect automatically and applies the correct formula for each lot. Select any individual lot from the results to explore its sign-by-sign and house-by-house interpretation in full.
The one-click calculator covers the Hermetic set plus Marriage and Exaltation. The wider Arabic Lots family also has focused calculators for the Lot of Children, Lot of Father, Lot of Mother, Lot of Siblings, Lot of Assets, and Lot of Manifestation so those topics can keep their own source notes and interpretation grids.
For the historical context, read how the lots were transmitted from Hellenistic Egypt through medieval Arabic astrology.

Frequently Asked Questions
Are Arabic Lots and Arabic Parts the same thing?
Yes. In modern English astrology, Arabic Lots and Arabic Parts usually refer to the same family of calculated points. Older Hellenistic sources often use the language of lots, while medieval Arabic and Latin transmission is why many modern readers know them as Arabic Parts.
Which lots and parts does this calculator include?
This umbrella calculator includes the 7 Hermetic Lots: Fortune, Spirit, Eros, Necessity, Courage, Victory, and Nemesis. It also includes the Lot of Marriage and Lot of Exaltation. Each result links to a focused calculator when you want the full sign and house interpretation for one lot.
Do I need an exact birth time to calculate Arabic Lots or Parts?
Yes. Most lots depend on the Ascendant, so they need birth time and birth location. A rough or unknown birth time can shift the Ascendant enough to change the lot degree, sign, or house.
How are the 7 Hermetic Lots different from individual Lot pages?
This page is the multi-lot calculator. It gives the set at a glance so you can compare themes across one chart. The individual Lot pages, such as Part of Fortune or Lot of Spirit, are better when you want a deeper interpretation grid, formula notes, and focused context for that one lot.
